*1 When the power supply voltage drops, the continuous running duty and the speed cannot be guaranteed.
*2 If the load to motor inertia ratio exceeds the indicated value, contact your local sales office.
*3 The shaft-through portion is excluded. IP classifies the degree of protection provided against the intrusion of solid objects and water in
electrical enclosures.
*4 The vibration directions are shown in the following figure. The value is the one at the part that indicates the maximum value (normally
the opposite to load-side bracket). When the rotary servo motor stops, fretting is likely to occur at the bearing. Therefore, suppress the
vibration to about half of the permissible value.
*5 V10 indicates that the amplitude of a rotary servo motor as a single unit is 10 m or less. The following figure shows the rotary servo
motor mounting position for measurement and the measuring position.
*6 Refer to the following for permissible load for the shaft.
Page 152 Permissible load for the output shaft
*7 Rotary servo motors with an oil seal have J in their model names.
*8 The values in ( ) are for when the torque is increased.
*9 If at 3000 r/min or less, the ratio will be 19 times or less.
*10 If at 3000 r/min or less, the ratio will be 20 times or less.
*11 If at 3000 r/min or less, the ratio will be 22 times or less.
*12 Refer to the following for geared servo motors.
Page 158 Geared servo motor
*13 Refer to the following for geared servo motors.
Page 158 Geared servo motor
*14 When a geared servo motor is used, the IP rating for the gear reducer area is equivalent to IP44.
